Package        : php5
Version        : 5.6.37+dfsg-0+deb8u1
CVE ID         : CVE-2018-14851 CVE-2018-14883
Debian Bug     : 890266


Two vulnerabilities have been discovered in php5, a server-side,
HTML-embedded scripting language.  One (CVE-2018-14851) results in a
potential denial of service (out-of-bounds read and application crash)
via a crafted JPEG file.  The other (CVE-2018-14883) is an Integer
Overflow that leads to a heap-based buffer over-read.

Additionally, a previously introduced patch for CVE-2017-7272 was found
to negatively affect existing PHP applications (#890266).  As a result
of the negative effects and the fact that the security team has marked
the CVE in question as "ignore," the patch has been dropped.

For Debian 8 "Jessie", these problems have been fixed in version
5.6.37+dfsg-0+deb8u1.

We recommend that you upgrade your php5 packages.
